Why Custom Attribution Windows?

Different ecommerce verticals and campaigns have varied conversion delay patterns. Standard fixed windows (e.g., 7-day last click) can misattribute sales, either inflating or undervaluing channel impact.

How Causality Engine Implements Custom Windows

Our platform allows you to define flexible attribution windows for each channel or campaign, specifying lookback durations that better reflect your typical customer buying cycle.

This customization enhances causal inference by aligning the counterfactual baseline period to realistic user behavior.

Key Benefits

Capture longer or shorter conversion delays accurately

Avoid crediting irrelevant touchpoints outside the window

Adapt attribution to seasonal or campaign-specific dynamics

How to Configure

In the dashboard, select each channel or campaign and specify start and end days for the attribution window. The Bayesian model then recalculates incremental impact accordingly.

Use Cases for Shopify Brands

Supplements brands with longer consideration periods

Fashion brands with short promotion cycles

Beauty brands running multi-touch campaigns
